Polyurethane valve rubber is an important part of fracturing pumps. It can operate stably under high pressure and high temperature conditions, and is an indispensable key accessory in oilfield development. Recently, there have been some new developments in polyurethane Val rubber materials, including material optimization and production process improvement. The following are some of the latest developments about polyurethane valve rubber for fracturing pumps.
- Material optimization
The main material of polyurethane Val rubber is polyurethane, and the optimization of the material can be realized by adjusting the ratio of the material and the production process. In recent years, more attention has been paid to the elastic modulus and wear resistance of polyurethane Val rubber. The research and improvement of these two indicators have achieved remarkable results.
In terms of elastic modulus, the elastic modulus of the material can be improved by increasing the content of hard components in the polyurethane material. In the research, the polymer polyurethane and the hard component grow through the reaction to form a polymer phase, thereby increasing the elastic modulus of the material. In terms of wear resistance, increasing the wear-resistant filler in the material can improve the wear resistance of polyurethane Val rubber. In the research, a variety of fillers including carbon black, nano-silica, etc. were selected for filling tests, and it was found that an appropriate amount of fillers can significantly improve the wear resistance of the material.
- Improvement of production process
In order to improve the quality of polyurethane Val rubber, the production process has also been improved. Common improvements include optimization of mold structure design, control of baking process, etc.
In terms of mold structure optimization, the use of numerical control machining technology to manufacture molds, and the use of curved surface processing technology can improve the precision and surface finish of molds. At the same time, a high-precision measuring system is used to check the quality of the mold surface, which can detect whether there are holes and defects, so as to ensure the production of high-quality polyurethane Val rubber.
In terms of baking process control, advanced control technology is used to control the temperature and time of the oven, which can ensure the suitability of heat treatment. During heat treatment, it is necessary to ensure that the material can be fully solidified and crystallized, otherwise its physical and chemical properties will be affected. By controlling the baking process, the quality of materials can be improved, production costs can be reduced, and quality loss can be reduced.
- New market demand
With the continuous advancement of technology and the increasing demand for oil and gas resource development, the market demand for the fracturing pump industry is also constantly evolving. In addition to the increase in demand, the market's requirements for product quality and performance are also getting higher and higher. This requires manufacturers of polyurethane vane rubber to continuously improve the quality level and technical content of their products.
In short, with the continuous advancement of technology and changes in market demand, polyurethane valve rubber for fracturing pumps will also continue to conduct technical research and optimization to meet the growing demand and improve market competitiveness.
